Powder Product

Cobalt-base Powder：

Cobalt-based alloy powder is a powder that is resistant to various types of wear and corrosion and high temperature oxidation. That is, the so-called cobalt chromium tungsten (molybdenum) powder alloy or Stellite alloy powder. The cobalt-based alloy powder contains cobalt as a main component and contains a considerable amount of nickel, chromium, tungsten and a small amount of alloying elements such as molybdenum, niobium, tantalum, titanium and niobium. The powder is used for hard surface surfacing, thermal spraying, spray welding and other processes, and can also be used for casting and forging parts and powder metallurgy parts. Suitable for valve manufacturing, turbine blades, engine valve screw pushers, rolling mill arches and other products.

Iron-base Powder：

Iron-based alloy powder adopts the gas atomization preparation method, and the hardness, compactness and bonding strength of the sprayed layer are equal to that of the nickel-based alloy powder coating, so the nickel-based alloy powder can be replaced in many occasions, but the toughness of the coating is lower than that. Nickel based alloy powder coating. The iron-based alloy powder coating has good wear resistance and is generally applied to wear resistance below 500 ° C at normal temperature.

(1) Carbon steel and low alloy powder: These materials are the most widely used mechanical engineering materials. It has good strength, wear resistance, wide source and low price. It is generally used for mechanical parts working at normal temperature, for hard surface coating of sliding surface and size repair of worn parts, but the melting point of such materials is higher, spraying It is easy to cause oxidation and porous coating.

(2) Iron-chromium-silicon alloy powder: This kind of alloy spray can obtain bright and dense coating and good processing finish. The hardness of the coating can reach 90HRB. It can be used to repair worn bronze and stainless steel parts. Used to repair cavitation in stainless steel containers, as a coating on the pump shaft, mechanical seal surface or motor shaft surface coating.

(3) Iron-chromium-boron-silicon alloy powder: This series of alloys has good wear resistance, pressure resistance and toughness, and is easy to process. It is used for wear parts and shaft pump surfaces, steam box housing sealing surfaces, etc. . Because it contains elements such as boron and silicon, it has self-fluxing properties and can be directly sprayed or remelted. It can be used for laser cladding.
